Given numbers are 642,411,186,556

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 642,411,186,556 is 757987572.

Find LCM of 642,411,186,556 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 107 x 137 x 31 x 278 = 757987572

Therefore, the lowest common multiple of 642,411,186,556 is 757987572.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

642 x 411 x 186 x 556 = 27287552592

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

642 : 1, 2, 3, 6, 107, 214, 321, 642

411 : 1, 3, 137, 411

186 : 1, 2, 3, 6, 31, 62, 93, 186

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,411,186,556, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

411:3x 137

186:2x 3x 31

556:2x 2x 139

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 27287552592/(1x36)

LCM = 27287552592/36

LCM = 757987572

Thus, we can understand that the LCM of 642,411,186,556 is 757987572.
